Redux Fundamentals, Part 8: Modern Redux with Redux Toolkit

• Redux Toolkit (RTK) is the standard way to write Redux logic
  • RTK includes APIs that simplify most Redux code
  • RTK wraps around the Redux core, and includes other useful packages
• configureStore sets up a Redux store with good defaults
  • Automatically combines slice reducers to create the root reducer
  • Automatically sets up the Redux DevTools Extension and debugging middleware
• createSlice simplifies writing Redux actions and reducers
  • Automatically generates action creators based on slice/reducer names
  • Reducers can “mutate” state inside createSlice using Immer
• createAsyncThunk generates thunks for async calls
  • Automatically generates a thunk + pending/fulfilled/rejected action creators
  • Dispatching the thunk runs your payload creator and dispatches the actions
  • Thunk actions can be handled in createSlice.extraReducers
• createEntityAdapter provides reducers + selectors for normalized state
  • Includes reducer functions for common tasks like adding/updating/removing items
  • Generates memoized selectors for selectAll and selectById
